LAMP-MOUNTING.

To all whom it may concern Be it known that I, ELLSWORTH A. HAW- rnonnn, a citizen of the United States, and a resident of Bridgeport, county of F airfield, and State of Connecticut, have invented an Improvement in Lamp-Mountings, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to lamp mountings, and more especially to a universally adjustable mounting, or bracket, for supporting a lamp upon the steering structure of a cycle.

My invention will be best understood by reference to the following specification, when taken in connection with the accompanying drawings of two specific embodiments thereof, while its scope will be more particularly pointed out in the appended claims:-

In the drawings: Figure 1 is a side elevation of a lamp mounting embodying my invention, showing in full lines the parts of the mounting in one position of adjustment, and in dotted lines such parts in another position of adjustment; Fig. 2 is a plan of the same; Fig. 3 is a detail sectional view on an enlarged scale on line 33 of Fig. 1; Fig. 4 is a detail sectional view on line 4P4 of Fig. 3; Fig. 5 is a side elevation of the mounting, slightly modified to adapt it to a different form of steering structure; and Fig. 6 is a plan of the same.

Referring to the drawings, wherein I have shown two forms of my invention for illustrative purposes, I have disclosed in Figs. 1 and 2 a portion of the steering structure of a motor cycle comprising a pair of members 77, which are herein disposed substantially parallel with each other, and are placed obliquely, as is customary with the steering structure of motor cycles.

In Figs. 5 and 6, I have shown a different form of steering structure, comprising a usual fork 8, swiveled in a fixed head 9, in front of which is a common form of spring casing 10 utilized as a part of the fork cushioning means. The two forms of steering structures shown serve to illustrate the diiferent conditions met in practice in providing mountings for lamps upon the steering structure of a motor cycle.

In Figs. 1, 2, 5 and 6, I have shown a lamp 11 of common form, which it is desired Specification of Letters Patent.

Serial No. 766,682.

to support upon the steering structure of a cycle. This lamp is provided as usual with a pair of lugs 12--12, by means of which the lamp may be supported upon its mountings. Somet1mes these lugs are placed vertically upon the lamp, and sometimes horizontally. In the present instance, the lugs are placed vertically, but it will be understood that the mounting is so constructed as to receive equally well lamps having vertically or horizontally disposed lugs. Each of the lugs 12 receives a lamp supporting post 13 of suitable form, the same being herein provided with a reduced portion 14 passing through its lug and having a threaded terminal portion 15, which receives a clamping nut 16, by means of which the lamp lug is secured to its post. The lamp supporting posts 1313 may be supported on arms 1717, respectively, in any suitable manner, but herein are pivoted thereon so as to be capable of being adjusted to vary the angular position of the lamp.

Referring more particularly to Figs. 3 and 4, the post 13 is provided with an ear 18, interposed between two ears 19 and on the forward end of the arms 17. A clamping bolt 21 passing through the ears 18, 19 and 20, is provided with a suitable nut, herein a wing-nut 22. If desired, the lamp supporting post may be secured in a fixed position, by simply having its ear 18 clamped between the ears 19 and 20 of the arms 17. Preferably, however, the bolt 21 is provided with a polygonal shank 23, fitting a corresponding perforation 24,- in the car 19, and is further provided with one or more teeth 25, adapted to interlock with suitable indentations 26 in the ear 18. Herein the latter is provided with a perforation of star-shaped outline, with the indentations 26 forming the points of the star. By this means, the lamp supporting post is positively locked, and yet may be angularly adjusted to various predetermined positions of adjustment by simply loosening the nut 22, withdrawing the teeth 25 from the indentations 26 in which they are looated, and then swinging the post to the desired angular position, after which the bolt is returned to its interlocking relation with the post, and the nut is screwed up tight to clamp the parts firmly.

Referring to the form shown in Figs. 1 and 2, herein the arms 17 are secured to the members 7 by clamps 27-27, each of which comprises two clampin members 28 and 29, the latter being provided with a tongue 30 passing through and interlocking with a lug 31 on the member 28. The clamping members 28 and 29 are further provided with cars 31 and 32, respectively, through which universal connections between the arms 17 and the supports 7, since the clamps 27 may be angularly adjusted about the axes of the members 7, while the arms 17 may be angularly adjusted about the axes of the bolts 38.

Referring to the form shown in Figs. 5 and'6, instead of employing two pairs of clamps for the attachment of the arms 17, I employ a single pair of clamping members '39 and 40, embracing the spring casing 10 and provided respectively with ears 4141 and 4242 to receive the threaded members or eye bolts 33. As a means for holding the arms 17 fixed in the desired angular position, I provide suitable brace means, herein comprising two braces 43, exactly similar to each other in construction. Only one of these braces shows in the drawings, but since they are identical, a detailed description of one will sufiice for both. The brace 43 has suitable provision for longitudinal adjustment, so that the lamp mounting may be adjusted to suit various conditions. Such longitudinal adjustment of the brace member may be effected by forming the same in two parts or members 44 and 45. The part 44 is provided with a longitudinal slot 46 and a perforation 47, while the part 45 is similarly provided with a longitudinal slot 48 and a perforation 49. A clamping bolt 50 passes through the perforation 47 and slot 48, while a second clamping bolt 51 passes through the perforations 49 and slot 46. By this means, the two parts of the brace are made adjustable one upon the other length wise, but are laterally rigid. The brace 43 may be pivotally attached to the arm 17 in any other suitable manner, but herein is provided with a perforation 52, through which the clam ping bolt 21, hereinbefore described, extends, said clamping bolt thus serving as ameans of attachment of the brace to the arm, as well as acting to secure thelamp supporting post in fixed position. Herein, the other end of the brace is adjustably secured to the adjacent supporting member 7 by a clamp 53, encircling the latter. This clamp may be, and preferably is, similar in construction to the clamps 27,

hereinbefore described, except that it is placed at right angles to the clamp 27, and is provided with a clamping bolt 54 passing through its ears, as well as through the brace 43, thus providing a means whereby the brace may be angularly adjusted about the axis of the member 7, as well as about the axis of the bolt 54. The described attachment, therefore, constitutes a universal of the parts in Fig. 1, it being evident that the clamps 27 and 53 may be vertically adjusted, and the threaded member 33 and braces 43 adjusted to correspond with the various positions of adjustment of the clamps. If the arms 17 and braces 43 are placed in the positions shownin dotted lines in Fig. 1, the lamp 11 will be tilted to the position shown in dotted lines in Fig. l. The adjustable mounting of the lamp sup porting posts 13 upon the arms 17 ,however, permits the lamp to be placed horizontally, if desired, regardless of the angular position of the arms 17, and moreover, the lamp may be angularly adjusted so as to alter the direction of its beam to quite an extent. As before stated, under some circumstances, lamps are provided with horizontal lugs, instead of the vertical lugs shown in the drawings. The mounting is capable of accommodating lamps of such construction, by simply adjusting the lamp supporting posts 13 to a horizontal, or substantially horizontal position. The width of lamps between their lugs often varies greatly, and the spacing of the members 7 of the motor cycle as well as their inclination, often varies greatly. It will be evident, however, that by the use of the described universal connections be tween the mounting and its support, and between the lamp and the mounting, the lat ter may be adjusted to a variety of positions within its range of adjustment to suit various conditions met in practice. The lamp mounting may also serve as a convenient support for the lamp supply means, as for example the generator or gas tank in the case of an acetylene gas lamp, or the battery in the case of an electriclamp. The latter type of lamp is shown in the drawings, and I have shown mounted upon. the

arms 17 a battery box 55 secured to a plate 56 resting upon the arms 17. As a means for ad ustably seeurlng the plate to the arms,

so as to permit the latter to be adjusted laterally, the plate may be provided with transverse slots 57 to receive clamping screws 58 threaded into the arms 17.

While I have herein shown and described two forms of my invention for illustrative purposes, and have disclosed and discussed in detail the construction and arrangement incidental to two specific applications thereof, it is to be understood that the invention is limited neither to the mere details or relative arrangement of parts, nor to its specific embodiments herein shown, but that extensive deviations from the illustrated forms or embodiments of the invention may be made without departing from the principles thereof.
